Abstract. Geomatics is trying to redefine its role in the Italian higher-level educational system according to the new technological developments. The recent thematic thread of Building Information Modelling (BIM) systems contributes to the new role of Geomatics inside universities and, more generally, in the training process. BIM systems propose new ways of managing the construction process throughout building life cycle, from design to construction and management. They allow managing large flows of information, organized and shared among the different operators in the construction chain, through databases linked to three-dimensional objects. The BIM approach is based on two principles: interoperability and digitization.BIM was born as an application dedicated to new buildings, to promote the optimization of the entire life cycle of the building, from design to management. Many countries have been active in this sector for years, while others are now joining the digitization approach. In this complex scenario, the proposal to adopt the BIM process not only for the management of new constructions but also for the intervention on the existing one, is relevant in a country, like Italy, with a very rich history and a high presence of built historical heritage. Maurice Murphy coined the term HBIM (Historic Building Information Modelling), referring to BIM systems applied to historical buildings that need intervention and subsequent management.Geomatics plays a crucial role in HBIM as it is the primary tool for the digitization of built heritage and to obtain a model of the existing, an "as-built" model. In order to achieve this result, laser scanner and photogrammetry are the main tools, and they are involved in the so-called Scan2Bim process. The other important role is connected with the modeling stage to arrive at a three-dimensional representation suitable for common BIM authoring software while maintaining the rigor and accuracy that characterize the geomatic approach.The fundamental role of Geomatics in this context requires the training of personnel specialized in surveying and managing the acquired data through HBIM systems. There are new training courses and masters in the field of BIM systems, hosted by Politecnico di Milano at the Mantua Campus, aimed at training new figures with a specific curriculum, including Geomatics.The elements that characterize the training course are the knowledge of the principles and methods of data and the evaluation of achievable accuracy and admissible errors. It is also important to address issues that are still not completely solved in HBIM community, such as the type of modeling the best levels of detail of geometric and information content and the most practical aspects of commercial BIM authoring software.The article describes the experience carried out by Politecnico di Milano and tries to define, afterward, the training curriculum for HBIM experts, in which Geomatics plays an essential role, not only in the data acquisition phase but also in geometric and informative modeling.

Asset Inventory

Building asset management is a system for organizing building assets in order to provide information to support decision making. One part of asset management is the inventory of building assets. Asset inventory can be done based on Building Information Modelling (BIM). BIM is one of the approaches to look at the building as a large unified database that can provide different information. The research case is theinventory of local government assets, especially state university assets because in Indonesia, state university assets belong to local government assets. The first step of local government asset inventory is to do three-dimensional modelling using a terrestrial laser scanner (TLS) assisted by Autodesk Revit. A textual database is created which contains the location code and item code on the asset referring to the Regulation of theMinister of the Home Affairs Number 108 Year 2016 on the Classification and Codification of Regional Property. The database is directly integrated with the threedimensional model of the building. By doing these two things, there will be a building asset management process that is integrated with BIM and can be used to plan assetdevelopment. ABSTRAK: Pengurusan aset bangunan adalah sistem untuk menganjurkan aset bangunan untuk memberikan maklumat untuk menyokong pengambilan keputusan. Satu bahagian pengurusan aset adalah inventori aset bangunan. Penyediaan aset boleh dilakukan berdasarkan Pemodelan Maklumat Bangunan (BIM). BIM adalah salah satu pendekatan untuk melihat bangunan sebagai pangkalan data bersatu yang besar yang dapat memberikan maklumat yang berbeza. Kes penyelidikan adalah untuk inventori aset kerajaan tempatan, terutamanya aset universiti negeri, kerana di Indonesia, aset universiti negeri adalah milik aset pemerintah daerah. Langkah pertama inventori aset kerajaan tempatan adalah melakukan pemodelan tiga dimensi menggunakan pengimbas laser bumi (TLS) yang dibantu oleh Autodesk Revit. Pangkalan data teks dicipta yangmengandungi kod lokasi dan kod item aset yang merujuk kepada Peraturan Menteri Dalam Negeri Nombor 108 Tahun 2016 tentang Klasifikasi dan Pengkodifikasi Harta Daerah. Pangkalan data secara langsung disepadukan dengan model tiga dimensi bangunan itu. Dengan melakukan dua perkara ini, akan membina proses pengurusan aset yang disatukan dengan BIM dan boleh digunakan untuk merancang pembangunan aset.

AbstractThere are several studies related to the cultural heritage digitization through HBIM (Heritage Building Information Modelling) techniques. Today, BIM (Building Information Modelling) software cannot represent old buildings with complex prominent and particularly detailed architecture perfectly, and multiple software are combined to obtain the buildings’ representation. In this paper, in order to find an alternative way of replicating the complex details present in antique buildings, a new methodology is presented. The methodology is based on a process of direct insertion of various 3D model parts (.obj), into a BIM environment. These 3D model elements, coming from the points cloud segmentation (from UAV and Laser Scanner), are transformed in intelligent objects and interconnected to form the smart model. The methodology allows to represent detail of the objects that make up an element of cultural heritage, although not standardizable in shape. Although this methodology allows to ensure a perfect reconstruction and digital preservation and to represent the different “defects” that represent and make unique a particular object of cultural heritage, it is not however fast compared with the traditional phases of point cloud tracing and more software are necessary for data processing. The proposed methodology was tested on two specific structures’ reconstruction in Reggio Calabria (South Italy): the Sant’Antonio Abate church and the Vitrioli’s portal.

Purpose This paper aims to develop a framework for optimising building performance through the integration between risk management (RM) and building information modelling (BIM) during the design process. Design/methodology/approach To achieve this aim, a research strategy consisting of literature review, case studies and survey questionnaire is designed to accomplish four objectives. First, to examine the concepts of design process, building performance, RM and BIM; second, to present three case studies to explain the role of using RM and BIM capabilities towards optimising building performance; third, to investigate the perception and application of architectural design firms in Egypt towards the role of RM and BIM for enhancing building performance during the design process; and finally, to develop a framework integrating RM and BIM during the design process as an approach for optimising building performance. Findings Through literature review, the research identified 18 risks that hamper optimising building performance during the design process. In addition, 11 building performance values and 20 BIM technologies were defined. Results of data analysis showed that “Design budget overrun”, “Lack of considering life cycle cost” and “Inefficient use of the design time” were ranked the highest risks that affect the optimisation of building performance. Respondents ranked “Risk avoid” or “Risk transfer” as the most risk responses adopted in the Egyptian context. In addition, “BIM As Built” was ranked the highest BIM technology used for overcoming risks during the design process. These findings necessitated taking action towards developing a framework to optimising building performance. Originality/value The research identified the risks that affect optimising building performance during the design process. It focuses on improving the design process through using the capabilities of BIM technologies towards overcoming these risks during the design process. The proposed framework which integrates RM and BIM represents a synthesis that is novel and creative in thought and adds value to the knowledge in a manner that has not previously occurred.

Building Information

With more than 80% of all construction projects overrunning their budget, there is a need for more efficient management of the estimated 10% of Gross Domestic Product (GDP) that is expended annually on construction across the world. It has been proposed that better information and data management through Building Information Modelling (BIM) will lead to cost savings and greater predictability. Notwithstanding the role of quantity surveyors (QS) in modelling and managing construction cost, they remain among the least capable of assimilating BIM into their existing traditional processes. Despite the increasing need for BIM capability assessments for projects, there remains, no tool specifically developed for assessing QS firm’s BIM utilisation capacity or performance. As a result, it is unclear the attributes that indicate BIM capability of QS firms as well as QS practices on projects. This study sought to address this through a review of BIM capability assessment frameworks in order to ascertain their suitability for QS practices. An expert focus group discussion was then used to identify peculiar attributes suitable for QS BIM capability assessment as a precursor to the development of a comprehensive model of QS BIM capability maturity. Findings reveal that most QS BIM capability attributes relate to processes including criteria for effective information definition and data management such that they are consistent with QS measurement standards. The BIM competence of staff also emerged as one of the key attributes highlighting the need for QSs to improve their knowledge, skills and experience in the application of BIM amidst current low levels of adoption. The proposed attributes would assist the development of performance and maturity indicators that would help QS firms better understand their own capability as well as the requirements for delivering costing services through BIM on projects.
